Thanks for you replies.
I set the parallel port on EPP and it seems OK.
The memory is external SRAM(4 x KM736V987) in address 0x10000000 and CS1 is enabled for it in config file:

; Chip select CS1 - external synchronous burst RAM
writemem.l  0x2fc10c  0xFF800000      ; OR1=0xFF800000
                                                         ; BSCY 0x#######E = 0x0 - 0-clock burst beat length
                                                         ; SCY  0x######F# = 0x0 - (2+SCY)*clock = 0 wait
                                                         ; AM   0xFFFE#### = 0xFFF80000 - 512 kByte
                                                         ;                 = 0xFFF00000 -   1 MByte
                                                         ;                 = 0xFFE00000 -   2 MByte
                                                         ;                 = 0xFFC00000 -   4 MByte
                                                         ;                 = 0xFF800000 -   8 MByte
                                                         ;                 = 0xFF000000 -  16 MByte
writemem.l  0x2fc108  0x10000001       ; BR1=0x10000001
;writemem.l 0x2fc108 0x10000001        ; BR1=0x00000001 relocation to base address 0x0
                                                         ; Bit 0x#######1 = 1 - region valid
                                                         ; Bit 0x#######2 = 0 - burst access enabled
                                                         ; Bit 0xFFFF#### = 0x1000 - Base address = 0x10000000

I select connect from debug menu and system connected,then in debug>EPPC>fill memory window set:
Memory Type:32 bit
Memory address:0x10000000
Memory Size:100

and it writes to memory(I can view).But when I check it for Memory size 0x8000 makes error and every thing goes wrong.  
I select the checkbox for 'verify memory writes',the verify fails.
PhyCORE has 4M SRAM and i don't know what make this errors?

Best Regards
Farzane
